Referring to the drawings, particularly Figs. 1 and 2, a sprayer attachment 10 for use for either spraying liquids, or when a foaming attachment 11 is provided, for foaming and spraying cleaning solutions or detergents, is shown. In this form, a'sprayer head 12 is shown as being detachably connected to a metal container 13 having a narrow-necked opening 14 to which the sprayer head is detachably connected by a complementally formed, threaded cap 15 which is similar to the conventional cap of the container. The container is adaptable either for holding paint, insect spray, varnish, cleaning, solution, etc., which may come'in the container as a particular product, or it may be a separate container sold with the spray gun, and which may be filled with the liquid which is to be sprayed or foamed. Although it is preferred to use a metal container of this form because.

it is inexpensive to manufacture and unbreakable, the sprayer head of this embodiment is adaptedby means ofthe depending cap 16 for use either with a glass container or with the metal container; and when used with aglass.

mental to the thread 16' of the glass jar illustrated in Fig. 4, .and the thread on the cap 16 may be. eitherroll;

threaded in place, or may be formed by indenting. in-

three equally spaced indentations 17, 17 and 1 7" to form:

a modified thread wherein the pitch of the thread on the portion forming the threaded cap 16. Although it is preferred to form the sprayer head from steel, it may be suitably formed, from brass, copper, or aluminum. The design of thesprayer head also permits it to be molded from a suitableplasticor die cast. It is preferred to brightzinc. plate the steel sprayer head, and then chrome dip-.topreservethe zinoplating. A disk or partition 19 is formed from thin gauge metal, such as aluminum or other suitable metal, and is formed with diametrically spaced lugs 20which are adapted to extend through openings 21 in, the intermediate flange between the upper cylindrical portion 18 and the cap 16. When assembled inposition, the lugs may be'staked to secure the partition in place.

The sprayer head 12 is provided with an outlet opening 22 and an inlet opening 23 diametrically opposite, which maybe either punched or suitably drilled to the required size. The opening 22 receives the tapered ferrule 24 of thefoaming attachment 11. The tapered ferrule permits the foaming attachment to be readily adapted forexisting sprayer headsformed with a similar opening and tube to that now in use. The ferrule 24 is provided with an opening 25 which extends about the end of. thezliquid spray tube 26, as shown in Fig. 1, to provide an annular passage 27 for the discharge of the air from the source of air to which the spray gun is attached, such'as from a vacuum cleaner.

The tube. 26extcnds downwardly into the container 13, as shown, and is affixed in position on the sprayer head by a tube support 28, which extends through complementally formed openings 29 in the caps 15 and 16. In assembling the caps 15' "and 16 together, they are mounted on the ferrule or tube support 28, and the free end of the tube support is staked over, as at 30, affixing the caps together. The tube is afiixed in place, as shown in Figs. 1 and 2, by deforming the tube support 28 from a cylindrically shaped member to a square-shaped portion, shown at 31, causing the tube to be complementally deformed at 32 to a similar square-shaped cross section. Removal of the tube is thus prevented, and the tube is rigidlyaflixed and aligned in position upon the sprayer head 12 with the upper end of the tube in axial alignment with the opening 22.

Each of the caps 15 and 16 is provided with an opening 33 to receive the valve rod 34 of the valve mechanism 35. The opening 33 is shaped as illustrated in Fig. 2 to receive the flattened portion 36, which serves to guide therod during its vertical. movement, and the rounded portion of the opening permits the entry of the threaded end 37 ,ofthe rod for mounting the thumb control nut or button 38. The lower end of the valve rod 34 is provided with a U-shaped end 39 over which a brass valve 40 is aflixed in axial alignment with the lower end of the tube 26 for the control of the liquid under pressure through the tube. The upper end of the valve rod extends through a compression spring 41, and is detachably affixed to the lower end of the thumb nut by: the turned boss 42 shaped as shown in Fig. 1. The upper end of the thumb nut 38.may be formed ,with "a head.

42"and, as shown, knurled, and it is preferred to form the thumb nut from round stock to the shape shown to extend througha complementally formed opening 43 in the sprayer head. In assembling the valve mechanism onflthe sprayer head, the valve 40 is first afilxed to the valve rod 34, andthe upper end of the valve rod is inserted through the opening 33, and with the valve inserted in, the tubeend, the .thumb nut is assembled in. position on thethreaded end 37 after the spring has been first afiixed to the end 42 of the thumb nut. The thumb nut is then adjusted on the valve rod to permit the valve to be adjusted with respect to the tube end for adjusting the flow of liquid under pressure through the tube. The amount of liquid sprayed may be adjusted by adjusting the thumb nut.

The valve 40 is preferably formed from rod stock, and is provided with a conical seat 44 and a tapered end 45. In the closed position, as shown in Fig. 1, the valve 44 seats against the end of the tube, and in the open position, the adjustment of the tapered end 45 within the tube, as controlled by the push button 42, determines the amount of liquid discharged from the spray gun. The valve 40 is provided with a;hole 46 complemental to the upturned end of the valve stem, and is affixed in place by pressing the valve on to the rod and, if necessary, may be staked in place.

Referring to Figs. '1, 2, and 3, there is illustrated a hose adapter 47 which is formed separately and detachably mounted within the opening 23 of the sprayer head. Securing means'48, preferably formed from rod stock in a screw machine, is inserted through complementally .formed openings 49 in the sprayer head and hose adapter at the upper end. At the lower end, the securing means is formed with a threaded stud 50, which extends through an opening 51 in the hose adapter, and is threadedinto a ferrule 52staked in position after mounting in complementally formed openings 53 in the caps 15 and 16. The ferrules 52 and 28 serve to affix the cap and disk 19 together, and when attached to the securing means 48 afiix the partition 19 to the sprayer head. The lugs 20 may or may not be staked over,

and when not staked, permit ease in the disassembly 'of the disk from the sprayer head for replacement and repair, if, necessary.

The outer end of the hose adapter is preferably formed with a tapered end 54, or it may beformed as a straight section 54", as shown in the dotted lines, and is particularly bent in the manner shown to provide a hand grip for the spray gun. In order to detachably connect the hose adapter 47 to a wand or hose end 55 of a vacuum cleaner hose, a tube 56 of plastic, or other suitable material, is cemented or clamped to the tube at the upper end 57, and the tube at the free end is-provided with a plastic ring 58 to which the tube is integrally molded. The ring 58 permits the tube to be rolled back upon itself to the dotted position 56, whereupon the hose end 55 is placed in position overlying the tapered end of the hose adapter, and the tubing rolled back to the solid line position, as shown, is of such size that there is a frictional fit between the hose end and the tube, and there is also enough stretch provided that different sizes and shapes of hose ends may be attached to the hose adapter. The friction is also such that the weight of the hose may be supported in the spraying operation.

The same connection is also provided if the hose adapter is formed from straight tubing, as shown in the dotted position 54. A hand grip is provided in the extended position of the tubing, and in this manner, the hand grip, when held by the operator, also provides a clamp be tween the ends of the adapter and hose end and the tubing.

Fig. 3 illustrates another embodiment of the coupling formed by the plastic tubing 56a, wherein the tubing is formed with a garter-type coiled spring 59 attached by turning over the end of the hose and seam welding it in position. The tubing 56a may be' rolled back into the dotted position 56b in order to couple the free end of the adapter 47 and the hose end 55' together, as described above. The, coiled spring 59 provides additional frictional grip, if necessary, for supporting the hose m spraying.

Although each of the embodiments of the coupling has been particularly described with reference to coupling a hose end and hose adapter of a spray gun together and .providing ,asealed joint, the coupling is equally, adapted for sealing the joints between the wands,.and also between a wand and hose end, and to provide sufficient friction in ajoint of this nature to prevent its uncoupling In use, the container 13 is filled with the liquid ,to be sprayed or :foamed and sprayed, and the hose connection is connected to a source of air under pressure by the hose adapter 47 and the coupling member '56. The usermay grasp the coupling member 56, and upon depressing the push button 42, the valve 46 is unseated, permitting the contents of the jar or container to be forced through the tube 26 as the contents of the container 13 are placed, under the pressure of air within the those, through the enlargedopening between the flattened portion 36 of the valve rod 34 and the hole 33. The air discharged through the spraying head from the hose adapter breaks up the liquid into minute particles, and sprays them upon the article to be sprayedas the air and liquid are discharged through the opening 22. Upon release of the push button42, the spring 41 biases the valve to its closed position, and the discharge of the sprayed liquid ceases.

In this same form, as illustrated in Fig. 1, when the foam sprayer 11 is in position, as illustrated'in .greater detail in Fig. 4, the spray gun is adapted for foaming and spraying the liquid as it is discharged from'thecontainer. The foam sprayer attachment comprises the ferrule 24 which istapered to1fit the-opening 22, and the center opening 25 provides an annular passage 27 for the discharge of the air under pressure from the vacuum cleaner, or other source of air pressure. Theferrule is staked in position in a cup-shaped member 60, the outer end of which is provided with an annular recess 61 in which is positioned a series of foraminous disks or screens 62. The disks are so shaped that they may be sprung into and out of position in the annular groove when it is desired to clean from the disks any dirt or dried residue left by the foamed liquid after using the foam sprayer attachment. When it is desired to use the spray gun simply as a liquid sprayer, the foam spray attachment 11 is readily detached, and may be attached through the frictional fit of the tapered end of the ferrule ,24 and the opening 22. The construction of the foam sprayer attachment may be from any suitable material which is readily drawn, and which does not corrode in use. Similarly, the disks or screens may be formed from any suitable non-corrosivemetal or plastic material which has sufiicient resiliency to be readily attached and detached to the open end ofthe cup-shaped member 60forming the foam spray attachment.

If desired, for certain detergent liquids to improve the foaming thereof, the foraminated disks or screens may be provided with preferably three, triangularly spaced dimples 62, Fig. 4, which permit nesting of the disks, as shown, or rearrangement to permit spacing of one or more of the disks, as desired. It is to be understood that other means will suggest itself to those 'skilledin'the art for permitting either nesting or spacing of the foraminated disks. It is aiso'within the scope of the invention that the foraminated disks may be used nested together without means for spacing them apart.

Referring to Figs. 4, 5, and 6, there'is illustrated another embodiment of the sprayhead which is adapted either for the spraying of liquid, or the foaming and spraying of liquid, as themodificationillustratedinjFig. 1 In this embodiment, similar orprimed*referencercharacters will indicate like or similar parts. The liquid tube 26' i is supported in position by a tube support 63 formed as illustrated in Figs, 4 and ,6, and extends through the modified partition plate'i9f and the'upper endofthe spray head 12' through'an opening. therein, wherein it 'is .staked 'over 'as "at 64. "The tube extends through the'hole's 6 5 and 66 inalignment with the opening 22 .81 11 .llPPfi end of the tube andwith'a hole 67in thepartition plate 19'. The valve rod 34 is similarly 'constructedas the embodiment :of Fig. '1, but is modifierlltherefrom in that ,the flattened end 36 is threaded at its upper end formount- .ing in the thumb nut 38', .which has a threaded opening -68 complemental to the thread of the valve rod 34. The

'. Ahose adapter 47' is provided with a tubular end 70 to extend through the opening 23 and with an enlarged end 71 which is adapted to fit a wand or hose 55 of .a vacuum cleaner hose to which the spray gun is attached. In this embodiment, the hose adapter may be interchanged with other hose adapters so that the preferred free end 71 may be selected which fits the form ofhose end or wand 55 of any particular type of vacuum cleaner, -It.:is customary in the vacuum cleaner art for each manufacturer to provide a wand or hose end different fromother manufacturers to prevent the interchange of cleaning tools. Previously this has required the fabrication of a .dilfer- .ent form of sprayer head for each make of cleaner. vIt is thus evident that by the present embodiment, it is possible to fabricate a common sprayer head requiring only the interchange of the hose adapter 47' to provide each manufacturer with a spray gun at reduced cost because of the simple construction. 7

Although it is possible to afiix the hose adapter inthe same manner as described with respect to the hose adapter of .Fig. l, a construction has been provided which further reduced the cost of the construction by deforming the partition 19 in the manner illustrated at 72 to provide a threaded opening 73 for the reception of a common 1 bolt 74 which extends through the threaded openings 73at the lower end, and at the upper end through an opening 49' in the sprayer head. In order to reinforce thetubular end 70, a bushing 75 is placed between diametrically opposite lugs 76 formed by deforming the tubeas shown. In assembling the different adapters in place, the adapter is inserted into the opening 23, and the bolt 74 is threaded in position. The bolt 74 also serves, along withthetube support 63, to afiix the partition plate 19' in position. In ,use, the cap 16 of the sprayer head 12' is threaded in .position on a glass jar 13' after a gasket 77 has been placed within the cap 16 to seal the liquid within the container. In the modification of Fig. 1, a similar gasket 77 is used if the sprayhead of this embodiment is affixed to a glass jar 13, and if it is used with a metal container 13, a gasket 77' is inserted in the cap.15. In the embodiment of Fig.1, the cap 15 permits themetal container to be supported by the cap and the can to be sealed against the gasket 77 of'the cap 16 as the can is assembled in the sprayer head 12 The operation of the embodiment of the sprayer head of Fig. 4 is=similar to that described with-respect 'tothe embodiment of Fig. l, with the exception that air pressure is appliedtoithe liquid through an opening 78 in the partition 19', rather than through the enlarged opening formedbetween the fflattened portion 36 and=the opening ,33 for the valve rod 34'. The controlof the flow :ofafluid is adjusted inthe same manner by adjusting the tension of the spring 41 by the thumb nut 33'. Howeventhe thumb nutnray provide,an additional function .in this embodimentin that, when the ,spray gun is,not being used but connected to ,a source of air under pressure, .the air is discharged through the openingzz, and through the :opening'68 provided in the thumb nut. The 'liquid in thecontainer is placed'under full pressure of the source of air --by placing the -thumb over the opening in the thumb not so that full air pressure is applied to the top of the liquid through the opening 77. The amount of liquid sprayed -or foamed is then controlled by the amount that ztheyalve .40 is opened. 'Normally,fithe spraygun is used withaslight amount of air bled :tothe atmosph h ou h t peningxlifi.

-rReferring to Fig. .7, th re is ill strate .a mo ification f the securing-;meaI1S.f r.a-. DS adan erfla- The foaming attachment 11.

adapter is similarly constructed as the embodiment of Fig. 4 with the exception that the holes '49.: are punched to receive the hexagonal securing means 48a. Thev sccuring means is threaded as illustrated to receive a machine screw 79. The securing means 48a is also provided with a coun'terbore 80, similar to that of the embodiment of Fig. 4,to receive the spring 41 when the securing means 48a is used as an embodiment of the thumb button 38".1When thesprayer head is constructed using the embodiment of the securing means of Fig. 7, it is evident that the cost of the sprayer head is reduced still further by the simplification of the reduction in the number of different parts. Referring to Fig. 8, there is illustrated a modified It is similarly constructed as that illustrated with the spray gun of Fig. 4. Therefore, the like or similar reference characters will indicate similarparts, and only the modified construction for the mounting of the foraminated disks 62a and 62b need be additionally described. The cup-shaped member 60' is preferably drawn with an enlarged opening 81 slightly tapered and large enough to permit entry of the alternate .screen disks 62a and 62b, preferably four in number.

-An-annular groove 82 is spun in the opening 81, which forms astop to prevent the disks from falling out, but permitting the flexible disks to enter easily into the annular groove 61. The foraminated disks 62b may be either formed with the triangular spaced dimples as Fig. 4, or as shownwith an annular raised portion 83 on one side and a dimple -84won the opposite side to properly space or' nest the foraminated disk. The disks may be otherwise rearranged, depending upon the liquid to be foamed. i

when it is desired to remove the foraminated disk in either of the embodiments of Figs. 4 or 8 for cleaning, the knurled securing means 48 is removed and inserted through the opening. 25. The length of the securing means 48 is such that the disks may be pushed outwardly, bending the disks so that they are readily detached from the annular groove 61 or 61"of each of the foaming attachments. The cleaned disks are replaced by snapping them back in position, and the, securing means 48 is repl-aced on the sprayer head. The machinebolt or screw 74 of the embodiment of Fig. 4 is of such a length that it may be similarly used to detach the foraminated disks or screens from the foaming attachment. The length and cross section of, the securing means 48a of the embodiment of Fig. 7 may be similarly formed to remove the disks. From the above, a simple arrangement which is always at hand may be used to remove the disks. for cleaning, although other suitable means are equally adaptable. i When using the embodiments of Figs. 1 and 2 as a foam sprayerlattachrnent, either of the containers 13 or,13 is filled with a suitable liquid cleaning compound or dc tergent, and air is admitted to the. sprayer head. By depressing the push button, the valve is unseated, permitting air under pressure to discharge the cleaning compound through the tube and into the foam sprayer attachment, where the liquid and the air discharged through the sprayer head encounters the several forarninated disks in the foam sprayer shell 60, and is blown through the perforations thereof. This causes the liquid to be agitated and broken down no a foaming condition either by the spaced, foraminated disks, or contiguously mounted disks. As the liquid is dischargedas foam, the air pressure also serves to spray the foamed liquid upon the surface to be cleaned.

Anysuitable liquid, cleaning compound which can be broken down into a foamed condition may be used. The compound may comprise a soapy solution, or it may be composed of chemicals such'as are used in the foam" methodof cleaning. Aspray gun equipped with the above'described attachment may be used to spray a clean- 8 ing compound foam upon carpets, rugs, upholstery, and many other objects.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention;

hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement, and combination of parts herein shown and described, or uses mentioned.
